BUILDING THE RIGHT REGRESSION

SUITE USING BEHAVIOR DRIVEN

TESTING (BDT)

TEST PYRAMID It is a concept Developed by

Mike Cohn. Depicts a structure on how

manual and automation tests should be aligned in the testing cycle.

Idea: We should have many more low-level unit tests than high level end-to-end tests running through a GUI.
